Bradley Cooper and Irina Shayk will reportedly try for another baby in 2018.
The 31-year-old Russian model already has a seven-month old daughter called Lea with the Hollywood star, and she's now looking forward to adding to their family.
A source said: "Both her and Bradley want another baby.
"They will be trying next year ... Irina loves being a mother."
Despite being new to parenthood, Irina and Bradley are successfully managing to balance their responsibilities to Lea with their own careers.
And until now, they've experience few problems dividing their time between London, Los Angeles and New York City.
The insider explained to E! News: "They both work together with their baby and are really the most loving and warm parents."
As well as doing their best for baby Lea, the couple also ensure they get to spend some quality time with each other, setting aside specific "date nights".
In spite of the challenges of parenthood, they remain as passionate about each other as they ever have done.
The source said: "The spark between them is still very strong. Bradley is crazy for Irina. He's madly in love with her.
"Bradley is the romantic type, while Irina wears the pants in the relationship. She is very head strong and an independent woman."
What's more, their families have also struck up a close bond since the high-profile duo started dating.
The insider shared: "Irina's mother and Bradley's mother spend a lot of time with them and they help out when Irina and Bradley are busy with work."
Shortly after Lea's arrival, it was claimed that Irina and Bradley had ambitions to have more children.
A source said at the time: "Bradley and Irina love each other so much and this is not gonna be the only kid - there will be a few more after this one."
